Product Description
Product Overview
It is generally used as a component that is cushioned at the workpiece connector and plays a role of precise adjustment of the clearance on the cushioned part.
It can also be used to protect the surface of the connected part from being scratched by the nut and disperse the pressure generated by the nut on the connected part.

Feature 1: High-precision products manufactured by cutting processes enable precise spatial adjustments.
Feature 2: Compared with standard washers, metal washers will not be dented after the connected part is screwed in due to the locking, and cause the bolts to loosen.
Feature 3: Compared with standard stamped washers, metal washers increase the friction with the mounting part, which can prevent loosening.

Usage Method
Example of use for securing the seat surface
■The bolt connection is stable.

Example of use as spring washer

■The bolt connection is stable.

Example of use for anti-loosening
■ By increasing the seat surface to increase friction, it is not prone to loosening.

■ By increasing the seat surface to increase friction, it is not prone to loosening.

Example of use for reinforcement of soft materials
■ Prevent the bolts from sinking in.

■ Prevent the bolts from sinking in.

Precautions
①Metal washer is a turned product, not a stamped part.
(2) When the relative humidity of the operating environment is high and certain anti-rust ability is required, please choose products with electroless nickel plating surface treatment or stainless steel SUS series materials.
(3) When the operating environment requires certain abrasion resistance and hardness for metal washers, please give priority to quenched products.
